UFEUS Grote (1878). 
Type: U. Satyricus Grote. 
A very flat-bodied, coarsely-haired genus with shiny feet and simple an- 
tenne, the middle and hind tibia spinose, as also the fore tibise in at least 
two of the species. The body is untufted, and in form the moths resem- 
ble Heliophila, and are classified by me at the end of the subfamily group. 
Nonagriing m. The naked eyes are lashed. The type is found in Canada, 
and the Northern States. I suspect it hibernates as a moth. The early 
stages are unknown.

4. U. Sagittarius Grote, Pap. III., 31. Jali fornia. 
The ornamentation is simple ; Satyricus, a large species, fuscous, with 
cloudy medial lines, unicolor smoky -fuscous, unlined, 
Plicatus is brownish-red with medial lines and varies in tint ; it is smaller 
than Sagittarius, which has red primaries with a yellow longitudinal 
streak on cell joining the bow-shaped yellow reniform, while beneath the 
secondaries have a thick triangulate mark. This species is the most inter- 
estingly marked in the genus. The flat form, coarse hair, strongly spinose 
and powerful feet are unmoth-like, and when I examined Satyricus I was 
reminded of a cockroach, though I confess it requires a strong imagina- 
tion to even suggest such a resemblance, 
FOTELLA Grote (1882). 
Type: F. Notalis Grote. 
This genus is related to Oaradrina, and has a slight correspondence to 
Acosmetia in form, the fringes are long on hind wings. Clypeus with a 
navel-shaped expansion, yes unlashed, naked. Ocelli, Wings full; 
the color and markings recall Bryophila Teratophora, Tibiee unarmed ; 
body slender, untufted ; vestiture silky.

ACERRA. Grote. 
Type: A. Normalis (rote. 
This genus is, I believe, synonymous with Perigrapha Led. Tt has the 
characters of Taniocampa, except that the body seems stouter and shorter, 
and there is a medial ridge on the thorax. Our species seem to differ by the 
impectinate J antenne. The Buropean species have large confluent stig - 
mata, and our first two species have them thus, and very prominently 
colored, the next two have them also coalesced, but not so prominent, and 
in the last two the stigmata are separate and inconspicuous, The genus 
seems to sustain a similar relation to Teniocampa, that Ammoconia does to 
Agrotis or Hpiglea to Glea.
